triac not firing due to snubber circuit i am using triac BTA16 800BW driven by MOC3041 for the snubber 220E resistor and0.01 1kv ceramic capactor. between terminals A1 & A2 of the triac. if i remove the snubber the triac works well switching the load.
pl. advice
as for now i am testing the circuit with a 20W bulb and am planning to run 1Kw motor using the circuit but when i use the snubber the bulb does not glow on testing with a line tester it shows current even if i remove the MOC3041 .

pl. explain about the type of capacitor used for the snubber
Consider the triac as a switch with sensitive current gain which latches (self-driven after trigger)
When you load the output with a snubber, you may need a little more drive current.
The MOC3041 is an opto-coupled zero crossing triac to drive power triac with 360R series for 220Vac and 180R for 120Vac.
I suspect your series R is too high so the drive current is too low and when snubber load was applied, it failed. Did you use 180K?
Is it wired correctly to pull up gate with 180R to HOT with 1K GATE to NEUTRAL to reinforce off state of phototriac by shunting leakage.
